Hello All,

I was fortunate today, I took my 300SD to a place in Boise called "Eurosport" and a technician listened to my clicking relay and found it to be the Alarm system (I didn't even know I had one duh). There is a black plastic piece under the front passenger side floor matt up by the firewall and under it is a small metal housed unit with a wire harness going to it, it was clicking away. Apparently a new unit costs $450 ! I do not need it and so we unplugged the harness which stopped the clicking. The tech said that on the older ones like mine that it would be ok to leave it unhooked because it is not tied to anything critical to the normal operation of the vehicle. He said that on a newer one that would be a problem since it is tied to the ignition etc. So anyway, no charge, no clicking, no alarm (must not have been working right anyway). Hope anyone else with similar problems may find this helpful.
